Point of no return passed.
There's a good sized rust hole on the passenger opera window... about 5 screwdriver sized holes there too. And grinding out the deeper rust pits is slow and tricky (I'm thinking about dissolving the rest with naval jelly applying filler and painting it. Patching the holes is going to be interesting.
There appears to be some rust under parts of the seam sealer. I'm wondering if I should buy some seam sealer to refill what I ground out or if Bondo is good enough.
The top part of the roof despite having only the thinnest overspray of paint and primer and having the worst degragation of the vinyl was actually the least rusty only having a couple small shallow surface splotches that I can sand off easily. That seems to be dud to Lincoln using fairly waterproof foam rubber for the top but essentially a stiffer version of cotton stuffing to pad the sides...the top padding insulates against water but the sides hold it to the metal like a damp sponge....if they had padded the entire vinyl roof with rubber it would not have rusted like this.
